Not necessarily, it could just be that we don't understand the mechanism of making fast decisions well enough. Many players with high APMs anecdotally report that it helps them maintain a quick response time. It could be that the jittering in an AI's command inputs is aligning to some quality of fast decision making that we don't understand, but the AI intuits.
Perhaps I wasn't clear: I'm saying that there is at least one contributing factor to humans clicking a lot, and that factor is NOT attributable to the human/computer player's thinking or decision process.
Rather, a fair portion of that churn is due to an inefficient communication system or control structure between the player and the game.
It's analogous to pitting an android against a human at racing an old car: Both of them will have a high volume of activity with their left foot on the clutch and right hand changing gears, but it doesn't reveal anything amazing about their thought-processes. It's simply what manual-transmission cars require in order to accomplish a certain task.
